GUN Worlds largest shotgun

This video shows what must be the world’s largest shotgun shell: the 120mm canister round designed for the cannon of an M1 Abrams tank. The 50 pound shell contains 1150 .40 caliber tungsten pellets launched at 4500 fps, with an effective range of 500 yards.

Very cool slow-motion video showing the path of the shot. The end bit is pretty neat as well

they may be more acurate but the fin-stabilized saboted rounds loose accuracy in a rifled barrel or so it was explained to me. They did make sabots that had bearing rings so they could be shot out of a rifled barrel without spining the penetrator.
